GPR158

GPR158 is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GPR158 rather than just read about it. In short: Probable G-protein coupled receptor 158 (GPR158), also known as the metabotropic glycine receptor (mGlyR), is a protein that in humans is encoded by the GPR158 gene. Function This protein is an orphan class C GPCR.

Key takeaways

GPR158 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GPR158 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GPR158 from memory before moving on to harder problems.

Reference excerpt

Probable G-protein coupled receptor 158 (GPR158), also known as the metabotropic glycine receptor (mGlyR), is a protein that in humans is encoded by the GPR158 gene.

Function This protein is an orphan class C GPCR. It is highly expressed in the brain, where it binds to RGS7, an inhibitor of Gi/o-coupled GPCR signaling, localizing it to the plasma membrane. It is expressed at lower levels in other organs and shows an unusual subcellular localization pattern, being found at both the plasma membrane and in the nucleus.

Clinical significance

Role in mood regulation GPR158 in the medial prefrontal cortex (mPFC) has been shown to regulate stress-induced depression in a mouse model of depression and has been found to be upregulated in post-mortem tissue samples from humans with major depressive disorder (MDD).

Role in prostate cancer The GPR158 gene is an androgen-regulated gene that stimulates cell proliferation in prostate cancer cell lines, and it is linked to neuroendocrine differentiation.

Worked examples

Example 1 — a first encounter with GPR158

Start with the simplest possible case. Write down what GPR158 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GPR158 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GPR158 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GPR158

In research: GPR158 appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses GPR158 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: GPR158 is common in secondary-school and first-year university syllabi. It links to neighbouring topics G protein-coupled receptors, Genes on human chromosome 10, Transmembrane receptor stubs, so understanding it makes those chapters shorter.
In everyday life: Look for GPR158 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GPR158 in simple terms?

Probable G-protein coupled receptor 158 (GPR158), also known as the metabotropic glycine receptor (mGlyR), is a protein that in humans is encoded by the GPR158 gene. Function This protein is an orphan class C GPCR.

Why does GPR158 matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GPR158?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
